The current study investigated these processes in a sample of 18 BPD patients and 18 matched healthy controls, using an event-related brain potentials methodology. Results revealed a reduction in the amplitude of the Feedback-Related Negativity of BPD patients, which is a neurophysiological index of the impact of negative feedback in reward-related tasks. This reduction, in the effect of negative feedback in BPD patients, was accompanied by a different behavioral pattern of risk choice compared to healthy participants. These findings confirm a dysfunctional reward system in BDP patients, which might compromise their capacity to build positive expectations of future rewards and decision making.9 p.application/pdfeng(c) Elsevier B.V., 2013Trastorns límits de la personalitatNeurofisiologiaReforç (Psicologia)Borderline personality disorderNeurophysiologyReinforcement (Psychology)info:eu-repo/semantics/article6290882021-11-23info:eu-repo/semantics/openAccess
